tion 9 sucks in air through the lateralopening 10 and when the pressureof the air'in the tank reaches a certain predetermined amount theball'check valve 11 prevents any outflow of water through the passag'e10, and also prevents such outflow when no water is flowing through theinspire-tor; By

7 means of this device suflicient air pressure is accumulate-cl andmaintained in the system to providethe necessary pressure before thepump starts. 7 Located in the tank is a controlling mechanism and switchwhereby the current to. thefmotor is cut off" when the water'reaches apredeterminedheightand whereby the current is turned on when the waterdrops below a certain-height .111 the tank. As a matter of fact thecapacity of the tank is preferably so small that the switch is operatedto throw in the current almost as soon as an outlet from the system is 0)ened and to break'the circuit ver 7 7- quicklyafter the outlet isclosed. Extending inward from the wall of the tank (Fig.

2) is a corrugated diaphragm 12 having its inner end 13-closed andcarrying the conifcal member. 1a. so that such conical member is movedendwlse by the movement of the end l3 offthe diaphragm. The end 13, is

' moved in and out by means of the float 15,

such float being carried upon bell crank leverlG pivoted at 17 to thebracket 18.-

" T he short end of the lever is connected to the V the drawing.

drops below a certain point'the float moves center of the end 13by meansof-the link 19.

The switchis preferably of the snap order and includes a spiral spring20 encircling the cone-shaped member li and coni'iecte'd to a collar2150 that the collar moves'endwise of themember i lfwith the spring. and23 area pair of contacts connected with the Wires24 and25 constituting apart of the motor circuit as diagrammatically shown in Then the Water inthe tank down causing the. end of the diaphragm 13 andthe member 14carried thereby to move to the right. Afterv the member'li is moved 1 sothat its central portion is to the right of "the spring 20, such springsuddenlymoves V the collar 21 to the left engaging the con- I 50' tacts22 and 23 and completing the circuit.

When the water rises above a predeter-- mined height in the tankthefioat causes a reverse movement of the member 14 and a consequentbreaking of the circuit.

In operating the system the opening or" one of the faucets l or 5permits flow of water due to the pressure accumulated in the tank Gr. 2

Such flow of water immediately lowers the'levelin the tank G and causesthe switch to operate as heretofore-setv forth completing the motorcircuit and starting the pumping elements. The inlet to the jet pumpispreit'erably provided with a ball check'va-lve a so'that the pipes 1and 2 are constantly full of water, keeping the sysupflow through thepipe 2 Ihigh'pressure pump 15.;

'tem primed; The starting of the motor,

therefore starts the operation of the rotary pumps B and 1), the pump Eforcing water down through the pipe 1 and causing an W while the'pinnp loperates" to distribute the waterthus raise h a part of the waterpassing through the distributing pipe F and another part proportionofair is always maintained in system is secured. V r 7 Fig.4.illustrates'in diagrammatic form a modification involving a single pump36 instead or" the two pumps of Fig. 1. In this the tank and thenecessary pressure in the construction 1 is the pipe leading upir'om thejetpump A, and2 and It" constitute the outlet pipes from-the pump 36.,The pipe '2 leadsdown into the well to operate the jet pump A while-thepipe F constitutes the distributing outlet connected to the'dis:

tributing tank G by neans 0t the pipe 7 carrying the inspiratcr 8, suchparts correspondingto similar parts in Figpl, and the operation of themotor drlvmgthe pump being the same, as in the construction heretoforedescribed. In this construction with a single pump a back pressure meansof the is necessaryin the pipe Fin order that sufficient pressure may beaccumulated in the pipe. 2 to operate the .jet pump -A, and this backpressure may be provided by plac ng a resistance means 44; in the. pipeF, whlch resistance means may, be a valve yieldingly reslsting thefiowof water through the-pipe or a reduction in the diameter of thepipeto throttle the flow. Thisis not as desirable an arrangement as theone constltuting the preferred embodiment of the inventionheretofore'described, but is'illustrated to. indi- Gate the scope of theinvention and the variety of arrangements possible. The construction hasone of the advantages incident to that of the construction of Fig. l ascompared to that of the patent, namelygthat the distributing tank G isplaced out of'the line of flow and may be made relatively small.

The advantages to this feature have already been set forth. V 3 Fig. 5illustrates another modification in .which the rotarypump 36 is drivenby an, electrlc inotor (not shown) and in which 2 is the outlet from thepump 36 leading intothe well for operating the jet pump A. The waterfrom the jet pump flows up through the pipe 1 and divides into twobranches, one part passing through the pipe 49 to supply the pump 36 andthe other part passing through the distributing pipe 13.

The distributing pipe has connected to it by the pipe 4 a distributingtank G; and such pipe carries an inspirator 8. These parts correspond.to similar parts as heretofore described in connection with Fig.1 andthe means 'for controlling themotor is the same. This construction issimpler than that of Fig. 1 but is not adapted for high lifts since theupward velocity through the pipe 1 is depended upon to distribute thewater. In the construction of Fig. 1 the water supplied to the lowpressure pump be lifted to any desired height by such pump, while thehlgh pressure pump supplies the pressure necessary to operate a jet atany depth, so that as compared with the 'constructlon of Fig. 5, thearrangement in pressure pumping element, a jet pump located in thesource of water supply, a pipe for supplying water under pressure fromthe high pressure pumping element to "the jet pump, a pipe forsupplying'the water lifted by the jet pump to the inlet side of the lowpressure pumping element, and connec "tions from the outlet side of thelow pressure pumping element for conducting a part of the water to theinlet side of the high pressure pumping element and a part to otherpoints for use. 1
